Profile: Harris' first full season in the majors was surprisingly good. He spent six-and-a-half years in the Colorado system before breaking in with the Rockies late in 2012. After being claimed by Arizona off waivers, Harris appeared in 61 games for the Diamondbacks and posted a sub-three ERA with above average strikeout and walk rates. But despite the good numbers, he's unlikely to have any fantasy relevance in 2013. Saves are almost assuredly out of the question for Harris, as Addison Reed was acquired in the offseason to close. And Brad Ziegler, David Hernandez and J.J. Putz are likely ahead of him on the depth chart should Reed lose the job or get injured. And those guys are all ahead of him for the setup roles as well, so Harris doesn't figure to have much value in holds leagues. To further illustrate this point, about 74% of Harris' work came when Arizona was trailing last year. He's a good bullpen arm, but not really someone you need to know about. (Brett Talley)

The Quick Opinion: Harris is an above average middle reliever. But there are too many guys in line in front of him for the fantasy relevant roles. In fact, about 74% of his work last year came when Arizona was trailing. Harris is unlikely to be all that relevant.

Profile: If you are reading this profile, you are either intrigued by this 31-year-old’s sub-two ERA in 2015 or he the fact that he was getting mentioned as an option in the Astros' closer role in the case of a Ken Giles injury. Either way, be prepared to be unimpressed. His 1.90 ERA was the only great aspect of his 2015 season. His ERA estimators point to a low to mid-three’s ERA which is in line with his career 3.28 ERA. He did have an extremely low .192 batting average on balls in play and an 87% strand rate last year, both of which should regress toward league averages and cost him in the ERA category. Among qualified relievers, his 16.7% strikeout minus walk rate ranked 55th in 2015. It is not a horrible value, but his lack of elite level strikeouts (projected at 8.9 strikeouts per nine) makes him unrosterable in most leagues. The only possibility for him to gain value is to fall into a closer role after injury now. With Houston’s addition of Ken Giles, his chances are about zero otherwise. (Jeff Zimmerman)

The Quick Opinion: Will Harris started the offseason with a chance of being the Astros' closer, but that dream died when the Astros traded for Ken Giles. Additionally, he really lacks the tools to even be a play in leagues that count holds.
